OESA-2024-2579 (CVE-2024-4109)

Vulnerability from osv_openeuler – Published: 2024-12-20 11:08 – Updated: 2026-08-06 11:08 – Source website

Summary

undertow security update

Details

Java web server using non-blocking IO

Security Fix(es):

Description: Product Security received a report that Undertow might incorrectly re-use an HTTP request header value from a previous stream for a request associated with a subsequent stream on the same HTTP/2 connection. The issue is linked to the readHpackString method and its interaction with the stringBuilder field. While such behavior typically results in an error followed by the termination of the HTTP/2 connection, it presents a potential vector for information leakage between requests. The original reporter referenced a similar issue in Apache Tomcat (CVE-2020-17527). In the patch for that vulnerability (https://github.com/apache/tomcat/commit/8d2fe6894d6e258a6d615d7f786acca80e6020cb) a StringBuilder field was improperly reused across multiple requests, leading to this issue. In the io.undertow.protocols.http2.HpackDecoder class of Undertow, within the readHpackString method, there is a code pattern identical to the one mentioned: for (int i = 0; i < length; ++i) { stringBuilder.append((char) buffer.get()); } String ret = stringBuilder.toString(); stringBuilder.setLength(0); if (ret.isEmpty()) { //return the interned empty string, rather than allocating a new one each time return ""; } Steps to reproduce: No reproducers or PoC were provided, this issue was identified through static testing. Affected versions: 2.2.x, 2.3.x, and 3.x(CVE-2024-4109)

Severity

7.5 (High)

The issue is linked to the readHpackString method and its interaction with the stringBuilder field. While such behavior typically results in an error followed by the termination of the HTTP/2 connection, it presents a potential vector for information leakage between requests.  The original reporter referenced a similar issue in Apache Tomcat (CVE-2020-17527). In the patch for that vulnerability (https://github.com/apache/tomcat/commit/8d2fe6894d6e258a6d615d7f786acca80e6020cb) a StringBuilder field was improperly reused across multiple requests, leading to this issue. In the io.undertow.protocols.http2.HpackDecoder class of Undertow, within the readHpackString method, there is a code pattern identical to the one mentioned:  ``` for (int i = 0; i \u0026lt; length; ++i) { stringBuilder.append((char) buffer.get()); } String ret = stringBuilder.toString(); stringBuilder.setLength(0); if (ret.isEmpty()) { //return the interned empty string, rather than allocating a new one each time return \u0026quot;\u0026quot;; } ```  Steps to reproduce: No reproducers or PoC were provided, this issue was identified through static testing.

CVE-2024-4109

[REJECTED CVE] A vulnerability has been identified in the Undertow package where the readHpackString method may incorrectly reuse an HTTP request header value from a previous stream for a new request on the same HTTP/2 connection due to improper handling of the stringBuilder field. While this typically results in an error and connection termination, an attacker could potentially exploit this flaw to leak sensitive information between requests within the same connection.
